Answer 2

Question :

A sheet in the form of a right triangle with hypotenuse 125m. If one of the sides is 75cm find the cost of fencing it at the rate of 4.50per m.

-------------

Before, finding the answer. Let's find out what we have to find in this answer.

• In this question, we are asked to find the cost of fencing.

________________

Given :

• Hypotenuse = 125 m
• Side = 75 cm

To find :

• the cost of fencing

Solution :

⇒ Let's first convert cm to m.

75 cm to m

= 75/100

= 0.75 m

⇒ Now, let's use the Pythagoras theorem to find the side.

c = a²+ b²

b = √125² + 75²

  = √15625 + 0.5625

  = √15625.5625

  = 125.0

⇒ Now, let's find the perimeter.

Perimeter = a + b + c

                = 125 + 125.0 + 75

                = 325 m

⇒ At last, let's find the cost of fencing.

Cost of fencing = 325 × 4.50

                         = 1462.5

• Therefore, the cost of fencing is Rs.1462.5.
